Toshiba 32LF221U21 screw size
M4 / M5 / M6 · 12 to 35 mm long
If you are replacing a screw on Toshiba 32LF221U21, the thread is M4, M5 and M6 in lengths from 12 to 35 mm.
There are 4 separate fitment records for it, including vesa mount (M4), stand (M4) and stand (M5), plus 1 more in the table below.
4 of the 4 records are marked confirmed, drawn from 1 source (files.bbystatic.com).
For reference, M4 is 4 mm across the threads at 0.7 mm pitch. The imperial size people confuse it with: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same.

How to check the screw before you buy
- For a wall or arm mount, the screw has to engage the threaded insert by several turns but must not bottom out, so measure the insert depth and add the thickness of the bracket and any spacers.
- Diameter: across the threads an M4 screw measures about 4 mm with calipers (usually a hair under). This device also uses M5 / M6, so measure each screw rather than assuming they match.
- Pitch: 0.7 mm from one thread crest to the next (14.29 crests per centimetre). A thread pitch gauge or the pitch-gauge tool settles it in seconds.
- Length: measure from under the head to the tip for pan, button, wafer and cap heads; countersunk (flat) heads are measured overall.
- The records span 12–35 mm, which means different positions take different lengths — match each hole to its own screw.
- Driver: the source does not name the drive. Standard M4 heads take PH2 for Phillips and T20 for Torx, and a 3 mm hex key for socket heads; a bit that fits loosely will cam out and strip the head.
- Tightening: no device-specific torque is published in these records. The site's general figure for M4 is about 2.0-3.0 N·m into metal threads and 0.8-1.4 N·m into plastic bosses; snug it up and stop.
Common mix-ups with M4 / M5 / M6
- VESA size follows the hole pattern, not the brand: MIS-D uses M4, MIS-E/F uses M6 or M8.
- The 'GoPro thread' is M5-0.8, a de facto standard on third-party mounts, and is not the imperial 1/4-20 tripod thread.
- VESA displays over 50kg move up to M8 x 1.25, which is outside metric M6 hardware - don't force an M6 bolt into a heavy-panel mount.

Questions about Toshiba 32LF221U21 screws
- What size screw does Toshiba 32LF221U21 use?
- M4 × 12 mm for vesa mount; M4 × 17 mm for stand; M5 × 17 mm for stand; M6 × 35 mm for vesa mount.
- How long are the screws in Toshiba 32LF221U21?
- The records range from 12 to 35 mm depending on the position, so match each screw to its own hole.
- What is the thread pitch of an M4 screw?
- 0.7 mm (coarse), which is the standard pitch for M4 machine screws; a 0.5 mm fine pitch exists but is uncommon. The tap drill is 3.3 mm and the normal clearance hole is 4.5 mm.
- What screwdriver do I need for Toshiba 32LF221U21?
- The sources do not name the drive. For M4, Phillips heads normally take PH2 and Torx heads T20; socket heads take a 3 mm hex key.
- Can I use an imperial screw instead of M4?
- No. Imperial look-alike: #8-32 (4.17 mm) — the standard US PC/rack screw, close but not the same. Use a true M4 screw so it does not cross-thread or strip the hole.
